You are a network technician working for a company that has decided to migrate from IPv4 to IPv6. In the interim, they must support both protocols (dual-stack). Three co-workers have called the help desk with problems and have received limited assistance. The help desk has escalated the matter to you, a Level 2 support technician. Your job is to locate the source of the problems and implement appropriate solutions.

b. Run more tests if it helps visualize the problem. Simulation mode is available.

Step 3: Propose a solution to solve the problem.

Make a list of things that could be changed to solve this problem. Start with the solution that is most likely to work.

Step 4: Implement the plan.

Try the most likely solution from the list. If it has already been tried, move on to the next solution.

Step 5: Verify the solution resolved the problem.

a. Repeat the tests from the help desk ticket. Did it solve the problem?

b. If the problem still exists, reverse the change if you are not sure it is correct and return to Step 4.

Step 6: Document the solution.

Record the solution to the problem. If you ever encounter the same problem again, your notes will be very valuable.
